If the tool is not 10, the arc power of the tooth head 10 in the direction of the tooth 10 of the arc 1 30 value 12 is set in the following paragraph. Technology] Since the beginning of civilization, hand tools have been possessed. Since then, wrenches have been the most t-handed in the field of hand tools, so almost all tools, furniture, or workstations that are commonly used in screw life have been used. The "wrench" with holes and nuts for the purpose of fixing or locking with 孔 has become a field work or loosening, especially after the concept of DIY is prevailing. Many consumers ’homes lack 3 Bolts and nuts with the same form and size as the hand, you can bring your own right winter's group. That is, according to the second figure and the second figure, there are different driving characteristics of the conventional swinging head wrench. The first patent No. 380468 shows the driving head 10. The driving head 10 is the pivot 11 and the outer part of the pivot 11 is The edge is formed as a circular arc surface, and there are teeth 12 on the entire surface. A pin hole is provided in the middle section of the pivot portion 11 horizontally. It should be noted that because the entire arc surface of the outer edge of the pivot portion 11 is provided with The flesh thickness of the pivot portion 11 is relatively reduced by ° due to the arrangement of the teeth 12, and the flesh thickness between the root of the teeth and the pin hole 13 is l. Referring to the third figure, the force state of the driving pivot 11 during the pulling operation is shown. When the swing head wrench is pulled clockwise, the force segments 133 and 3b of the drive head 10 will directly receive the force-bearing force segment 1 The meat thickness L of 3 b is reduced by the setting of the teeth 1 2.

Description of the invention (2) When the pulling force applied to the swing head wrench is too large, the meat wall of the force section 13b may have cracks 14 or the possibility of damage, which seriously affects the torque value that the wrench can withstand. . The most important torque value of the wrench is sacrificed for the setting of the positioning structure, which is obviously a bottom-up design. Referring to the third and fourth illustrations, a driving head 20 of another conventional swinging wrench is shown. As shown in the patent case No. 421111 of Annex II, the lower part of the driving head 20 is set as the pivot part 21, and the crotch part 21 The outer edge of the arc surface is formed with a circular arc surface, the left half of the arc surface is provided with teeth 22, the right half of the arc surface is provided with a relatively constricted arc surface 23, and a pin is provided in the middle of the pivot portion 21 and transversely Hole 24. Because the left half of the outer edge of the pivot portion is provided with the teeth 12, the meat thickness of the left half ^ is relatively reduced due to the province of the teeth 12, and the meat thickness between the root of the tooth 22 and the pin hole 24 is l. At the same time, referring to the sixth figure of Annex II, it is important to 'when the stopper slides to the right half of the outer edge of the pivot 1, in order to make the drive head 20 rotate freely, The right half needs to be set to a more indented circular arc surface 23. It is worth noting that the circular arc surface 23 must be slightly lower than the root of the tooth 21 in order for the restraint to slide to the right. If the arcuate surface 23 is set slightly higher than the tooth root of the tooth 21, the control plane ^ will be blocked by the arcuate surface 23 and cannot slide onto the arcuate surface 23. Therefore, the meat thickness at the right half of the outer edge of the pivot portion 21 is reduced more than the left half, and the meat thickness between the arc surface 23 and the pin hole 24 is L1 (L1 < L). Referring to the fifth figure, the force state of the pivot portion 21 of the drive head 20 during the pulling operation is shown. When the swing head wrench is turned clockwise < clockwise, the force segments 24a, 24b of the drive head 20 will Take the pull force directly. However, the meat thickness L1 of the stressed section 24b is greatly reduced due to the structural limitation. Therefore, when the pulling force applied to the swing head wrench is too large, the meat wall of the stressed section 24b is liable to produce cracks 25 or damage, which seriously affects The value of the third invention (3) on page 6 that the wrench can withstand is obviously set and sacrificed the various dm designs of the wrench's most important torque. The above-mentioned conventional swing-head wrench is lost but it is necessary to improve it. question. The present invention intends to eliminate or at least alleviate the problems encountered in the prior art. [Summary of the Invention] The technical problems to be solved in the "backhand improvement structure" are limited, so that the tooth root and the round structure of the swing force of the swing head wrench can be used to = Thickness: Reduced. When read, it is easy to produce cracks or damage, and the extreme value of the meat wall on the severely stressed section. Jiuli's shirt rings to the torque that the wrench can withstand. 2 An improved structure of the swinging wrench. The pivot of the driving head is formed as 0 solitary surface. The first part of the pivot is provided with teeth, and the pivot Part: One: The circular arc surface of the portion is full meat thickness, without any reduction in meat thickness, the circle = face = hole, and the meat thickness is L2 (L2 > L > L1). When the wrenching force is applied to the pendulum and the wrench, the thick meat wall of the force section can withstand large forces, and it is not easy to generate cracks or damage, which effectively increases the torque value that the swinging wrench can withstand. The teeth provided on the first part of the pivot portion of the driving head may be concave teeth or semi-inner teeth. The tooth roots of the teeth are lower than the arc surface of the second portion of the pivot portion. The arrows on the drive head are the same, and the arc surface of the second part of the pivot is full-thick.
